tcpdump vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 14.10
– Ubuntu 14.04 LTS
– Ubuntu 12.04 LTS
Summary:
tcpdump could be made to crash or run programs if it received specially
crafted network traffic.
Software Description:
– tcpdump: command-line network traffic analyzer
Details:
It was discovered that tcpdump incorrectly handled printing certain
packets. A remote attacker could use this issue to cause tcpdump to crash,
resulting in a denial of service, or possibly execute arbitrary code.
In the default installation, attackers would be isolated by the tcpdump
AppArmor profile.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.10:
tcpdump 4.6.2-1ubuntu1.2
Ubuntu 14.04 LTS:
tcpdump 4.5.1-2ubuntu1.2
Ubuntu 12.04 LTS:
tcpdump 4.2.1-1ubuntu2.2
In general, a standard system update will make all the necessary changes.
